Thanks for the heads up. After chatting with @LostMarine , I am so tempted to finally start modding the E90 M3. I might go ahead with the full Evolve XPipe with 200CEL cats, then further down the road, the Evolve E-Tronic Muffler.

Haha...I told myself a long time ago to keep the E90 stock, but it's becoming harder and harder to fight the urge. After seeing @LostMarine 's awesome 60-130mph time with his bolt ons and tune, I felt like getting an XPipe is just a must!

I think the difference in power gains comparing a oem xpipe with deleted cats vs an expensive aftermarket xpipe that also deletes the oem cats is negligible. You may gain slightly more power with the latter, but you wont ever tell the difference from SOYP.
